/* during shutdown, there are two relevant timeouts. One is
 * NM_SHUTDOWN_TIMEOUT_MS which is plenty of time, that we give for all
 * actions to complete. Of course, during shutdown components should hurry
 * to cleanup.
 *
 * When we initiate shutdown, we should start killing child processes
 * with SIGTERM. If they don't complete within NM_SHUTDOWN_TIMEOUT_MS, we send
 * SIGKILL.
 *
 * After NM_SHUTDOWN_TIMEOUT_MS, NetworkManager will however not yet terminate right
 * away. It iterates the mainloop for another NM_SHUTDOWN_TIMEOUT_MS_EXTRA. This
 * should give time to reap the child process (after SIGKILL).
 *
 * So, the maximum time we should wait before sending SIGKILL should be at most
 * NM_SHUTDOWN_TIMEOUT_MS.
